Abstract:
The purpose of this paper is to investigate whether the minima in hydrodynamic resistance can be predicted
to occur at the same angles of heel and trim in the case of bare hull towing tank tests, bare hull simulations
and appendage and leeway simulations. If so, the appendages and the leeway can be rejected from future
investigations, which would prove a beneficial advancement, as they impose further complexity to
simulations. The results of verification and validation (V&V) included in this paper demonstrate that the
numerical method predicted too low resistance. Though the study identifies and systematically investigates
possible sources of error, the major source of error was not found. These various possible sources of errors
were identified for further research, and as future references for similar cases. Moreover, the simulation
results for the variations of heel and trim also require further study. Before a full set of results is available,
one cannot make conclusions regardin
g the angles of heel and trim that lead to minimal resistance. This
paper discusses the results and potential avenues of future research, and is a result of an initiative at
Chalmers University of Technology focusing on sports and technology.
